Marlborough MA Building Permits

If you live in Marlborough and plan any work on your house, you will likely need a permit. Here is what you need to know.

Work That Requires a Permit

- Additions of any size

  • Decks over 30 inches above grade
  • Roof replacements (tear-off)
  • Siding replacement
  • Window replacement (in most cases)
  • Structural alteration (removing walls, adding load)
  • Basement finishing
  • Bathroom or kitchen renovation involving plumbing/electrical
  • Sheds over 200 sq ft
  • Garages (attached or detached)
  • New HVAC equipment
  • Pools (above or in-ground)
  • Solar panel installation

    Work That Usually Does NOT Require a Permit

    - Replacing kitchen cabinets without moving plumbing/electrical

  • Interior painting and flooring (no structural)
  • Replacing fixtures in existing locations
  • Like-for-like appliance replacement
  • Small landscape work
  • Sheds under 200 sq ft (verify with the Building Dept)

    When in doubt: call the Marlborough Building Department at 508-460-3760 and ask. They will tell you straight.

    Typical Turnaround Times

    Standard permits in Marlborough typically take 5-10 business days for approval after a complete application. Larger projects (additions, new construction) can take 2-4 weeks if planning board or zoning board review is needed.

    Common Causes of Delay

    ❌ Incomplete site plans (missing setbacks, dimensions) ❌ Missing contractor license documentation ❌ Improper structural drawings ❌ Setback violations requiring zoning review ❌ Historic district properties (if applicable) ❌ Missing certificate of insurance
